feat(ai): 敌人感知↔状态模型——待机/警觉/追击/巡逻 + 可复用感知状态机

感知门面 EnemyBase.InChaseZone(追逐/aggro)/InVisionZone(视野/los,缺省回退aggro),纯查询;
转换逻辑归 AI 层: 新增可复用 PerceptionStateMachine(统一规则,HasAlert/视野缺省自动降级);
规则: 未发现进视野→警觉, 进追逐→追击(委托能力), 追击脱离视野→巡逻(永不回警觉,再进视野再警觉).
EnemyStatsSO.HasAlertState 勾选项; ContactChaseAbility 改纯执行器(退出由AI中断); E001 用可复用件.
PlayMode 验证四态转换全通过.
